GASeBURNER.

SPECIFICATION forming part of Letters Patent No. 369,421, dated September 6, 1887.

Application tiled August 9, 1886. Serial No. 210.487. (No model.)

To @ZZ whom it may concern:

Be it known that I, AUGUST F. ZIMMER- Lire, of Milwaukee, in the county of Milwaukee and State of XVisconsin, have invented newr and useful Improvementsin Gas-Burners; and I do hereby declare the following to be a full, clear, and exact description of said invention, reference being had to the accompanying drawings, and to the letters or gures of reference marked thereon, which form a part of this specification.

Figure l of theaccompanying drawings represents a vertical section of my invention and Figs. 2, 3, and 4 are details.

Like parts are represented by the same reference-letters throughout the several views.

A is the combustionchamber of myburner, into which gas is admitted through the small central opening, B, at the apex of the cone C from the gas-pipe M, While a large volume of air is admitted freely through the open bottom of the chamber A and mingles with the gas in its escape through the flame-openings D.,

The neck E of the chamber A is so reduced in size as to contract the stream of the upwardescaping gas, thus increasing the force of its current, whereby alarge volume of air is drawn up into the chamber and mingled and consumed with thegas. The openingl is closed by turning down the cap C upon the stationary stop F, and the escape of gas is nicely adjusted to any desired quantity by turning said cap upward or downward upon the screw-threaded thimble G. The stop F is supported in the thimble G upon the cross-bar H, which bar is permanently attached to said thimble.

Then the cone C is once properly adjusted to admit the required proportion of gas for the air admitted to produce the desired dame and the most economical results, the cap may be left at rest, and the gas may be turned on and oft thereafter by opening and closing the stopcock I in thc pipe.

To facilita-te turning the cone C when ad justing it, the same is attached to the handwheel J. The wheel J serves the twofold purpose of turning the cone C when adjusting it and that of supporting the chamber A, which rests upon it. Upwardprojecting lugs Kare formed upon the upper edges of the arms of 5o the Wheel J,Which serves to retain the chamber A in position centrally above the cone C. Knobs L are formed upon the periphery of the wheel J, by which it is turned.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a gasburner, the combination of the combustion-chamber A, having a series of apertures around its top and an enlarged open 6o bottom, screw-threaded gas tube or thimble G, rigidly aixed to the gas-pipe M, gaspipe M, screw-threaded cone C, iitted upon the screwthreaded surface of the ihimble G and provided with an aperture at its apex, stop F, fitted to the aperture in said cone O, and hand-Wheel J, affixed to said cone C and supporting said chamber A centrally above said cone, substantially as and for the purpose set forth.

2. The combination of the stationary screW- 7o threaded thimble G, stop I?, rigidly affixed to the interior Walls of said thimble, screwthreaded cone C, fitted to said thimble G, hand-Wheel J, afixed to the cone G, and combustion-chamber A, supported above said cone G upon said hand-wheel A, substantially as shown and described.

3. The combination of the screw-threaded t-himble G, stop F, screw-threaded cone C,

hand-wheel J, chamber A, gas-pipe M, and so
